ファインダ光学系２１はそのまま使用できる。Therefore, the light incident on the observation image from the endoscope eyepiece to the TV camera body 11 is split into two parts by the beam splitter 18, and one of the lights is sent to the image sensor 20 via the imaging optical system 19.
The other image is formed on the camera eyepiece 16 via the finder optical system 21. Therefore, the finder image divided on the finder optical system 21 side is transferred to the image carrier optical system 19.
The light enters the finder optical system 21 from the incident light side of the 'a image element block 37 without passing through it. Therefore, it is possible to change the size of the image corresponding to the size of the image observed with the endoscope eyepiece, and the size of the silver image element 20 is changed, and the image sensor 20 is replaced with one of a different size. However, the observed image from the camera eyepiece 16 does not change. That is, when an M-type element with excellent performance is developed and the conventional image sensor 20 is replaced with a new one, the finder optical system 21 can be used as is by replacing only the unitized image sensor block 37. .

is screwed into the threaded portion 25 of the fixed frame 22.
Since the lens frame 26 is installed to enable IIR, the AM element block 3 can be removed by removing the lens frame 26 from the fixed frame 22.
The entire image carrier optical system 7 can be separated from the image carrier optical system. Even if the silver image element 20 is replaced with a new one and the size of the image sensor 20 is different from the previous one, the observed image of the camera eyepiece 16 of the finder optical system 21 remains unchanged. The image can be observed in a size corresponding to the size of the observation image of the J2 mirror eyepiece.
